**AD22103KRZ: Analog Devices' Precision Temperature Sensor with Voltage Output**

The **AD22103KRZ** from Analog Devices represents a significant advancement in the field of precision temperature sensing. This integrated circuit (IC) is engineered to provide a highly accurate, linear voltage output that is directly proportional to the ambient temperature, making it an indispensable component for a wide array of applications requiring reliable thermal monitoring.

At its core, the AD22103KRZ is a **monolithic temperature sensor** with an on-chip signal conditioning circuit. Unlike thermistors or other discrete solutions that require complex calibration, this sensor is pre-calibrated during manufacture, offering a plug-and-play simplicity that significantly reduces design time and complexity. Its operating range from **0°C to +100°C** is ideal for numerous industrial, consumer, and commercial systems where monitoring within this span is critical.

A key feature of the AD22103KRZ is its **ratiometric voltage output**. The sensor is powered by a single +3.0 V to +6.0 V supply, and its output voltage scales linearly with both the supply voltage and the temperature. This ratiometric characteristic provides inherent immunity to noise on the power supply line, enhancing measurement stability and accuracy in electrically noisy environments. The output transfer function is designed for ease of use, typically providing a slope of **22.5 mV/°C** with a DC offset of 500 mV at 0°C, resulting in an output of 500 mV at 0°C and 2.75 V at 100°C.

The precision of the AD22103KRZ is noteworthy, boasting an initial accuracy of **±2.5°C** at full scale. This level of accuracy is sufficient for the vast majority of monitoring and control applications, from environmental control systems to battery management and process control. Its low power consumption and robust performance make it equally suitable for portable, battery-powered devices as it is for harsh industrial settings.

Housed in a surface-mount **SOIC package**, the sensor is designed for modern PCB assembly processes. Its small form factor allows for flexible placement close to the heat source being measured, ensuring a fast response time and minimizing errors caused by thermal gradients.

**ICGOOODFIND**: The AD22103KRZ stands out as a highly integrated, accurate, and easy-to-use solution for temperature measurement. Its ratiometric voltage output, wide operating voltage range, and factory calibration eliminate the need for additional circuitry, making it a superior choice for designers seeking to enhance system reliability while simplifying the design process.
